JAMES NEAL AND CHARLES W. EMERY, OF BOSTON, MASSACHUSETTS.

PUMP.

Specification of Letters Patent No. 14,029', dated January 1, 1856.

To all whom t may concern:

Be it' known that we, JAMES NEAL and CHARLES W. EMERY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Pumps for Elevating Vater or other Fluids; and we do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure l denotes a front elevation of our improved pump. Fig. 2, is a vert-ical and central section of it.

In the said drawings, A, denotes the barrel of the pump, which is screwed (as seen at, c, en) down into the base or supporting plate B and against the lower valve plate when it is supported on a circular shelf C thro-ugh which the water or fluid ascends to the body of the pump, when said pump is in use.

The discharging nose of the pump is seen at D, as projecting from the air fountain or reservoir E fixed on the top of the barrel. The neck Z (Z or upper part of the base is made cylindrical and so as to receive upon it an annular collar or ring F which is placed and made to encircle and turn freely on it and is fastened in any position on it by a set-.screw G, which is screwed through said coller and against the neck. To opposite sides of this collar or ring, the brake posts H I are jointed and they extend upward and are respectively jointed at their upper ends to two brake levers L, M, whose inferior or inner arms are jointed to the head of the piston rod K, the joints of the brake posts being such as to permit each of the posts to be moved freely either toward or away from the pump barrel as occasionI may require during the working of the brakes.

As the pump barrel is independent of or separate from the base on which it rests,-

and is screwed into it and down upon the valve packing or ring in order to make a tight joint, it will be seen that from time to time the posit-ion of the nose of the pump with respect to the brakes is liable to variation. Now in case the pump barrel is so applied to a separate base plate if the brake or pump lever were supported directly on the pump barrel or on the cap plate thereof, the movements of and strains on the brakes during` the operation of the pump would tend to turn the pump barrel in the base plate and work it loose in the socket thereof. By applying the brake posts to a collar supported on the base plate as specified not only are we enabled to adjust the nose in any position with respect to the brakes, but to operate the brakes without danger' of turning the pump barrel in its socket so as to cause the joint of the two to leak.

We are aware that the lever or levers for working the piston rod of a pump have been supported either on the pump barrel or on a rotary cap plate fitted on the top of said barrel; we therefore do not claim such, but

That we do claim as our invention is- Supporting the brake posts by means of an annulus or ring made to encircle and rotate on the neck of the base plate or stand of the pump barrel when the pump barrel is applied to the base plate so that it may turn independently on said base plate and be screwed or fastened to it as described.

In testimony whereof we have hereunto set our signatures this fourth day of August A. D. 1854i.

JAMES NEAL. CHARLES W. EMERY.
